Why Choose Us

Four Reasons Our Foundation Crack Repair Clients Don't Call Anyone Else

Not every Cottage Grove, MN foundation crack needs the same material or approach. A vertical settlement crack behaves differently than a stair-step block crack, and we adjust injection technique and material to match what's actually happening in the wall.

1

Licensed Crack Classification

Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.

2

Fast Local Response

Most crack injection appointments can be scheduled within a day or two of your call.

3

Flat-Rate Injection Pricing

A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.

4

Epoxy & Polyurethane Both On the Truck

Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.

What We Do

The Full Scope of Our Cottage Grove, MN Foundation Crack Repair Work

Every Cottage Grove, MN Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.

Crack Repair

Low-Pressure Epoxy Injection

Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.

Crack Repair

Polyurethane Injection for Active Leaks

Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.

Crack Repair

Stair-Step Block Crack Repair

We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.

Crack Repair

Vertical & Horizontal Wall Crack Sealing

We document crack width and location with photos before and after injection so you have a record of the repair.

Crack Repair

Pre-Sale Crack Inspection & Documentation

Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.

How It Works

Our Four-Step Foundation Crack Repair Dispatch Process

01

Call & Crack Description

Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.

02

On-Site Crack Classification

A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.

03

Written Injection Quote

You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.

04

Injection & Cure Verification

We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.

★★★★★

"Crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."

"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."

— Cottage Grove Homeowner

★★★★★

"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."

FAQ

Frequently Asked Questions About Foundation Crack Repair

How do you classify contaminated water versus a structural crack repair?▼

Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.

Will you repair hairline cracks or only large ones?▼

Catching a crack early with injection usually costs less than waiting until it's actively leaking.

Is epoxy or polyurethane better for my crack?▼

We make the call on-site after inspecting the crack, not before we've seen it.

How long does crack injection take?▼

Most single-crack injections are completed in a few hours during one visit.

Will the crack reopen after injection?▼

If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.

Do you provide documentation for real estate transactions?▼

Yes — we provide before-and-after photos and a repair summary that Cottage Grove, MN buyers, sellers, and lenders commonly request.
